SUPPORT FOR INDEX CARDS.

Application filed December 5, 1921. Serial No. 520,187.

To a]? whom-1'1 may concern:

Be it known that I, GEORGE H. DAwsoNaai reference being bad to theaccompanying drawings, and to the numerals ofreferen'ce marked thereon,which form a part 'ofthis specification. I This invention relates tovisible index 35 cards which are mounted in overlapping relation in atray or the like. and this'invention concerns itself primarily witl'i. te nieans for and manner of removably ii'ioun ting the index cards.

This invention comprises the novel features of construction andmechanisms-hereinafter described and more particularly pointed out anddefined in the appended claims.

In the accompanying drawings which illustrate certain preferredembodinien-tsof my invention and in which similar reference numeralsrefer to similar features the different views:

Figure 11 is an end elevational view of a ledger sheet which may beused.

Figure 12 is a fragmentary plan view partly in section illustratingcertain features oftfhe 'fojirjm shown in Figure 10. .Assliown on thedrawings: .jl-nreferrnig to Figures 1 to 4. it will be observedthat tliecard support comprises a flexible hingeuniemhjer .1 preferably of sized.fabric l avinglp'rojectiofns. 2 extending there- 'from 'whicli' in theprose the form of eyelets tol rich are secured zit instance are inelements 3 and extendin arallel thereto. The elements 3 in Figure lcomprise flaps which are integral with the hinge member 1 and folded orsuperimposed thereover from the lateral edges. Fousimplicity ofconstruction, I may use the-staples 4 shown in Figures 7 to 9 instead ofthe i ets 2 for providing the card-holding prd ei. ions and anchoringmeans for theflzips 1 In Figures 5 and 6. there isill-iistrated aslightly modified form of device comprising an elongated metal strip 5embedded in the fabric hinge 5 by pasting. a suitable strip 6 over theback of the hinge. the embedded portion being substantially equal to thedistance between the eyelets Q. -'-And at each end, the strip isprovided with a projection 7 extending through-the fabric and ahorizontal element 3 spaced slightly from the front face of the hingeand extending parallel thereto. In this instance;- the projection 7 andelements 8 are formed-bybending the ends of the strip in substantiallythe form of hooks.

The index .card'fl that is designed to be used with the aforedescribe'dcard supports is provided with elongated --i iotchcs or slots 10 at theupper latter edges as shown in Figure 3. the distance between thenotches approximating the distance between the projections 2. 4 or T.The cards are adapted to x be mounted upon their supports by flexing thesame. A simple way consists of first 'sliding one end of the eard underthe elemeiit 3 or 8 so that the projections 2. 4: or 7 villenter theslot 10 and then flexing the ca 'dslightly so that the other end may be,

folded ledger sheet 11 which may be used in in)" visible index system byproviding notches iii the upper lateral edges-j. When such ledger sheetsare used. the retaining elements 12 which, are flaps on the hinge nt'einber 1 for holding the sheetson the projections 2 downwardly attheir lower edges so as to fa cilitate the insertion of the sheetthereunder. It will accordingly be observed that the construction of theelements or flaps 1; is such that the upper ends and corners of the fold'ed ledger sheets will be eil'ectively held together and protected fromcrimping over or having dog ears formed thereon, and for iir creasingthe flexibility of the hinge member 1 a slot 1% may be provided in thecenter just below the supporting bar 15.

The flexible hinge members in all the forms are secured to supportingand spacing bars similar to the bar 15 of Figure 10 which are adapted tobe inserted in guide channels in a tray as is well known in the art.

It will accordingly be observed that my invention provides a simple cardsupport that etl'ectively retains a card or ledger sheet thereon andfrom which the same is removable by a slight flexing movement. It is obvious that by forming the flaps according to the form shown in Figure10, very thin cards or folded sheets can be readily used.

' I am aware that numerous details of construction may be varied througha wide range without departing from the principles 0t this invention,and l therefore do not purmesses pose limiting the patent grantedotherwise than necessitated by the prior art.

I claim as my inyentionz l. The combination with a notched card, of asupport therefor comprising flexible hinge member having projections forreceiving the notches on said card and holding the same in suspendedrelation and means attached to said projections for retaining the 'ardon said support. l

2. The combination with a notched card, of a support therefor comprisinga fabric strip having projections for engaging the notches in said cardfor suspending the same on said fabric strip, and elements extendingparallel to said strip and spaced slightly therefrom for receiving-saidcard'tliereunder.

The combination with a notched card, of a support therefor comprisingaflexible strip having inwardly extending flaps on its lateral edges forreceiving the card thereunder, and studs extending through said flapsand strip for engaging the notches in said card and holding the same insuspended relation. 1

In testimony whereof I have hereunto subscribed n'iy name in thepresence of two subscribing witnesses.
